SYNOPSIS
$number = sig_num $name;
$name = sig_name $number;
sig_translate_setup;
$number = $Sig_num{$name};
$name = $Sig_name[$number];
DESCRIPTION
This module contains utility functions for dealing with signals.Nothing is exported by default.
- sig_num chopped-signal-name
-
Returns the signal number of the signal whose name (sans "SIG") is
chopped-signal-name, or undef if there is no such signal.
This function is prototyped to take a single scalar argument.
- sig_name signal-number
-
Returns the chopped signal name (like "HUP") of signal number
signal-number, or undef if there is no such signal.
This function is prototyped to take a single scalar argument.
- sig_translate_setup
-
If you want to use the @Sig_name and %Sig_num variables directly you must
call sig_translate_setup to initialize them. This isn't necessary if
you only use the function interfaces sig_name() and sig_num().
This function is prototyped to take no arguments.
- %Sig_num
- A hash with chopped signal name keys (like "HUP") and integer signal number values.
- @Sig_name
- An array mapping signal numbers to chopped signal names (like "HUP").
